WALL-PAPER-PASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 471,958, dated March 29, 1892.

Application filed January 16, 1892- Serial No. 418,277- (No model.)

provements in WVall-Paper-Pasting Machines,

\ of which the following is a specification.

This invention relates to machines for applying paste or other adhesive substance to strips or rolls of paper designed for wall-coverings and'other purposes.

The object of the invention is to provide a simple, efficient, and easily-operated machine whereby the preparation of paste or other adhesive or glutinous material will be applied evenly and smoothlyby means of a pastedistributing roller having a less rate of speed than a moving strip of paper, though actuated therefrom, thus insuring a thorough and uniform application of the adhesive material.

My invention consists in the several novel features of construction and combinations of devices in a pasting-machine for applying adhesive substances to wall-papers and other strips of paper, as hereinafter more fully set forth.

In the annexed drawings, illustrating the invention, Figure 1 is a perspective of my improved pasting-machine. Fig. 2 is a vertical transverse section of the same. Fig. 3 is an end elevation of the machine with one of the rollers raised or removed from its bearings to permit insertion of the paper beneath said roller.

Referring to the drawings, the numeral 1 designates an oblong box or paste-receptacle, which may be of sufficient capacity to contain the quantity of paste required in papering a room of ordinary size. In one side of this box, and extended from end to end thereof, is journaled a paste-distributing roller 2' of large diameter. This roller is so arranged as to take up the paste in the box or receptacle and apply it to the back of the paper, and it is my purpose to so control and retard the rotation of the said roller while the strip of paper is being drawn through the machine as to cause a uniform distribution of the paste.

For the purpose of crushing any lumps of glutinous substance in the paste, a roller 3, Fig. 2, is arranged in contact with the disbeing forced backward. It will be seen that I as the paste is carried upward on the distributing-roller 2 the adjacent crushing-roller 3 will exert just sufficient pressure to break gup any lumps or semi-solid substance and cause the paste to be spread on the large distributing-roller.

The roll of paper or to which paste is to be applied is placed on a rod or shaft 6, that is preferably swiveled or pivotally attached at one end in some suitable manner to an arm 8, projecting from one corner of the paste-receptacle. The other end of the rod or shaft 6 is loosely held in an open-ended slot 9, formed in an arm 10 at the opposite end of the apparatns. The swiveled or pivotal attachment of this rod or shaft -6.at one end permits it to be swung outward at its other end for placing and removing a roll of paper, and as the said rod or shaft is also free to rotate with the unrolling of the paper it is obvious thatit will not exert any friction to retard the drawing of the paper through the machine.

In preparing the machine for operation the free end of the paper a is drawn upward and carried over a guide-roller 11, that is journaled in the upper ends of yielding standards 12, the lower ends of which are pivotally attached to, preferably, the arms Sand '10 at the opposite ends of the paste receptacle. From the guide-roller 11 the paper is drawn downward beneath a removable guide and pressure roller 13, and thence over the top of the paste-distributing roller 2, as shown in Fig. 2. TherollerlSis-journaled in bearings 14. at the top of each end of the box or receptacle 1 and is made removable from its bearings, so that it can be lifted out of place, as shown in Fig. 3, to facilitate placing the paper across the top of the paste-distributing roller 2 before putting the machine 1p operation. After the paper has been arranged across the top of the distributing-roller 2 the roller 13 will be replaced in its bearings 14 and will then serve as a guide-roller to secure proper contact of the back of the paper with the paste on the distributingroller.

The paste-distributing roller 2 is provided at one end with a peripherally-grooved pulley 15 of large diameter, and a similar pulley 16 of smaller diameter is formed on or attached to one end of the yielding guide-roller 11, as shown in Fig. 1. These pulleys 15 and 16 are connected, as shown in Figs. 1 and 3, by a belt or cord 17, which is slack when the roller is removed from its bearings, owing to the yielding standards in which the roller 11 is supported; but when the roller 13 is replaced the pressure thereby exerted on the roller 1 1 forces it back and tightens the belt orcord 17 on the pulleys 15 and 16, s0 that now while the paper is being drawn through the machine for the purpose of applying paste thereto the motion imparted by the moving strip of paper to the guide-roller 11, which is of comparatively small diameter, will cause the belt or cord 17 to exert a retarding effect oh the rotation of the paste-distributin g roller, which is of much larger diameter than the guide-roller to which it is belted. Besides tightening the belt or cord 17, the pressure exerted by the roller 13 causes the paper to lie evenly and smoothly in contact with the rollers 2 and 11 and permits a steady unwinding of the roll a as the paper is drawn through the machine. A spring 18, Figs. 1 and 2, is arranged in engagement with the yielding or pivoted standard 12 at one end of the roller 11, opposite the attachment of the retarding belt or cord 17, for the, purpose of supporting that end of the roller 11 against theoutward pressure of the roller 13 when the latter is in place.

By retarding the rotation of the paste-distributing roller 2, as above described,so that will be removed at a less rate of speed than the strip of paper in contact therewith, the

paste will be applied evenly and thoroughly to. the back of the paper.

At the exit side of the box 1 is a stationary smoothing rod or plate 19, having a rounded surface over which the paper is drawn outward on its way to an exit guide-roller 20, which is removably supported in bearings 21, attached to the opposite ends of the box. The guide-roller 20 is so located and arranged as to cause the back of the strip of paper to pass in close contact with the rounded surface of the rod or plate 19, and thereby more perfectly smooth the paste thereon. The bearings 21 for the exit guide-roller 20 may be pivoted at 22 and provided with adj ustingslots 23 and screws 24, so that the roller-bearings can be adjusted vertically to cause the moving strip of paper to bear more or less on the smoothing rod or plate 19, according to the consistency of the paste or glutinous material employed.

In order to compensate for any stretching of the belt or cord 17 by long use, the bearings ll of the rollcr13 maybe made separate from the box 1 and pivotally attached thereto by screws 25, that will permit any required adjustment to increase the pressure of the roller 13 on the roller 11 and thereby tighten the belt.

The machine is made ready for use by placing it on a stand or 'table 26 of suitable height, where it can be held securely by means of hooks 27, projecting from a rod 28, journalcd at the lower edge of the box 1 on one side in such position that the said hooks may be turned down and made to engage the edge of the table, as shown in Figs. 2 and 3, where they will exert sullicient friction to hold the apparatus in place. By removing the roller 13 from its bearings suilicient space will be afforded for replenishing the paste-receptacle when required.

The manner of operating the machine for applying paste or adhesive material to astrip of paper will be readily understood from the foregoing description, it being only necessary to draw the paper a through the machine by hand in the direction indicated by the arrow in Fig. 2, and as the paste is applied the pa per can be cut olt' into suitable lengths for its intended uses, whether as a wall-covering or otherwise. 7

hat I claim as my invention is 1. In a pasting-machine, the combination of a paste-receptacle, a paste-distributing roller journaled in said receptacle and adaptpaper, a pressure-roller acting on the paper,

3 and a retarding belt or cord connecting the paste distributing and guide rollers and adapted to exert a retarding etlect on the r0- tation of the paste-distributing roller, where by it will be moved at a less rate of speed than the said strip of paper, substantially as described.

2. In a pasting-machine, the combination of a paste-receptacle, a pastedistributing roller journaled in said receptacle, a guideroller journaled in yielding or pivoted standards and rotated by a moving strip of paper, a retarding belt or cord connecting said rollers, and a removable roller intermediate the said guide-roller and distributing-roller and adapted to exert a pressure on the guideroller to force it backward and tighten the retarding belt or cord, whereby said belt or cord is made to exert a retarding action on the rotation of the paste-distributing roller,so that it will be moved at a less rate of speed than the paper strip, substantially as described.

In a paper-pasting machine, the combination, with a paste'receptacle, of a paste-distributin g roller therein, a guide-roller rotated by the moving strip of paper, a pressure-roller acting on the paper, a retarding-belt connecting the guide-roller with the paste-distributin g roller and operating to retard the rotation of the latter so that it moves at a speed less than the paper, and a paste-equalizing and lump-crushing roller acting on the paste-distributing'roller above the level of the paste therein, substantially as described.

4. In a pasting-machine, the combination of apaste-receptacle, a paste-distributing roller journaled in the said receptacle, a revolving paste-equalizing and lump-crushing roller located in contact with the paste-distributing roller and journaled in pivoted swinging bearings suspended in the paste-receptacle, and stops engaged with said pivoted hearings to hold the crushing-roller in place, substantially as described.

5. In a pasting-machine, the combination of a paste-receptacle, a paste-distributing roller journaled in said receptacle, a guideroller supported in yielding or pivoted bearings'and rotated by a moving strip of paper, the said guide-roller being of less diameter than the strip of paper, and a spring engaged with one of the yielding standards of the guide-roller to support said guide-roller against the pressure of the intermediate removable roller, substantially as described.

In testimony whereof I have hereunto set my hand and affixed my seal in presence of 35 two subscribing witnesses.
